CLEANING AND MAINTENANCE OF CERAMIC-GLASS HOB
Ceramic glass hob should be cleaned only when completely cooled down, preferably
after each use, otherwise even the slightest stains remaining after cooking may burn
into the hob surface with each following use.
For regular maintenance of ceramic-glass hob use special cleansing agents, produced
in such way to create protective film upon the surface.
Before each use, wipe the dust and other particles from the hob, they may scratch the
surface (Fig. 1).
Fig.1
Caution: use of steel wool, abrasive cleaning sponges, and abrasive detergents can
scratch the surface of the hob. The surface may also be damaged by the use of
aggressive sprays and inappropriate liquid chemicals (Fig.1 and 2).
Pattern marks can be erased by the use of aggressive cleansing agents or rough and
damaged cookware bottoms (Fig. 2).
Minor stains are removed with moist soft cloth; after that the surface should be wiped
dry (Fig. 3).

Water stains are removed with gentle vinegar solution, but you must not wipe the frame
with it (certain models only), since it may lose its glow. Never use any aggressive
sprays or limestone removers (Fig. 3).
Major stains are removed with special ceramic-glass cleansers.
Follow strictly the manufacturer's instructions.
Be careful to remove any remains of cleansing agent from the hob surface, otherwise
they will be heated during the next use and can damage the hob (Fig. 3).

Stubborn and burnt stains are removed with special ceramic-glass scraper. Be careful,
however, not to touch the hotplate surface with the scraper handle (Fig. 4).
Handle the scraper with utmost care to avoid injuries!
Sugar and sugar containing food may permanently damage the ceramic-glass hob
surface (Fig. 5), so the remains of sugar and sugar containing food must be scraped off
from the hob surface immediately, when the hotplates are still hot (Fig. 4).

Discoloring of ceramic-glass hob has no effect whatsoever on its operation and stability.
In most cases, it appears as the consequence of burnt in food remains, or as a result of
dragging pots and pans (especially aluminium or copper bottom cookware) across the
surface, and such discoloring is rather hard to remove.
Note: All described faults are mostly esthetical and do not affect directly the operation
of the appliance. Remedy of such faults is not covered by warranty.
